ESD SENSITIVITY CAUTION  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.

300mA, Ultra-Low Noise, Low Dropout,  
RF Linear Regulator in Ultra-Thin Package  
SGM2041  
APPLICATION INFORMATION  
The SGM2041 is an ultra-low noise and low dropout  
LDO and provides 300mA output current. These  
features make the device a reliable solution to solve  
many challenging problems in the generation of clean  
and accurate power supply. The high performance also  
makes the SGM2041 useful in a variety of applications.  
The SGM2041 provides the protection functions for  
output overload, output short-circuit condition and  
overheating.  
transistor is active to discharge the output voltage  
through a 255Ω (TYP) resistor.  
When the EN pin voltage is higher than 1V, the device  
is in active state, the output voltage is regulated to  
expected value and the automatic discharge transistor  
is turned off.  
The EN pin is pulled down by internal 0.03μA (TYP)  
current source when the EN pin is floated. This current  
source will ensure the SGM2041 in shutdown state and  
reduce the power dissipation in system.  
The SGM2041 provides an EN pin as an external chip  
enable control to enable/disable the device. When the  
regulator is in shutdown state, the shutdown current  
consumes as low as 0.03μA (TYP).  
Reverse Current Protection  
The PMOS power transistor has an inherent body  
diode. This body diode will be forward biased when  
VOUT > VIN. When VOUT > VIN, the reverse current  
flowing from the OUT pin to the IN pin will damage the  
SGM2041V. If VOUT > VIN event would happen in  
system, one external diode will be added between OUT  
pin and IN pin in circuit design to protect the  
SGM2041V.  
Input Capacitor Selection (CIN)  
The input decoupling capacitor should be placed as  
close as possible to the IN pin for ensuring the device  
stability. 1μF or larger X7R or X5R ceramic capacitor is  
selected to get good dynamic performance.  
When VIN is required to provide large current  
instantaneously, a large effective input capacitor is  
required. Multiple input capacitors can limit the input  
tracking inductance. Adding more input capacitors is  
available to restrict the ringing and to keep it below the  
device absolute maximum ratings.

Output Capacitor Selection (COUT  
)
The output capacitor should be placed as close as  
possible to the OUT pin. 1μF or larger X7R or X5R  
ceramic capacitor is selected to get good dynamic  
performance. The minimum effective capacitance of  
COUT that SGM2041 can remain stable is 0.5μF. For  
ceramic capacitor, temperature, DC bias and package  
size will change the effective capacitance, so enough  
margin of COUT must be considered in design.  
Additionally, COUT with larger capacitance and lower  
ESR will help increase the high frequency PSRR and  
improve the load transient response.

Negatively Biased Output  
When the output voltage is negative, the chip may not  
start up due to parasitic effects. Ensure that the output  
is greater than -0.3V under all conditions. If negatively  
biased output is excessive and expected in the  
application, a Schottky diode can be added between  
the OUT pin and GND pin.

starts the thermal shutdown function and turns the pass  
element off.  
Output Current Limit and Short-Circuit  
Protection  
When overload events happen, the output current is  
internally limited to 580mA (TYP). When the OUT pin is  
shorted to ground, the short-circuit protection will limit  
the output current to 360mA (TYP).  
Therefore, thermal analysis for the chosen application is  
important to guarantee reliable performance over all  
conditions. To guarantee reliable operation, the junction  
temperature of the SGM2041 must not exceed +125.  
Thermal Shutdown  
The maximum allowable power dissipation depends on  
the thermal resistance of the IC package, the PCB  
layout, the rate of surrounding airflow, and the  
difference between the junction temperature and  
ambient temperature. The maximum power dissipation  
can be approximated using the following equation:  
The SGM2041 can detect the temperature of die. When  
the die temperature exceeds the threshold value of  
thermal shutdown, the SGM2041 will be in shutdown  
state and it will remain in this state until the die  
temperature decreases to +140.  
PD(MAX) = (TJ(MAX) - TA)/θJA  
(1)  
Power Dissipation (PD)  
Thermal protection limits power dissipation in the  
SGM2041. When power dissipation on pass element  
(PD = (VIN - VOUT) × IOUT) is too much and the operating  
junction temperature exceeds +160, the OTP circuit  
where TJ(MAX) is the maximum junction temperature, TA  
is the ambient temperature, and θJA is the  
junction-to-ambient thermal resistance.
